  • Publication number: 20120029724
    Abstract: A method and system for controlling temperature in an electric vehicle battery pack which preserves battery pack performance and longevity while maximizing vehicle driving range. A controller prescribes a minimum allowable operating temperature in the battery pack, where the minimum operating temperature increases as battery pack state of charge and remaining useful life decrease. During vehicle driving operations, the minimum allowable temperature is computed, and a thermal management system is used to warm the battery pack only if necessary to raise its temperature above the calculated minimum level. By minimizing use of the thermal management system to warm the battery pack, energy consumption is reduced and vehicle driving range is increased, while not adversely affecting battery pack performance or durability. The same strategy is employed during charging, which reduces the amount of energy consumed from the grid for warming the battery pack.

    Abstract: A circuit affixed to a moving part of an engine for sensing and processing the temperature of the part. The circuit generates a signal representative of the temperature sensed by a thermocouple (110) and amplified by an amplifier (112). A square wave oscillator (113) with a temperature sensitive capacitor (C8) varies its frequency in response to changes of a local temperature of the circuit. A chopper (114, J27) converts the output of the amplifier into an alternating current signal. The chopper is gated by the square wave oscillator and a second input is coupled to an output of the amplifier. Thus, the chopper has an output signal having a frequency representative of the local temperature and an amplitude representative of the thermocouple temperature, whereby the combined signals represent the true temperature of the part.

In accordance with the invention, the system provides driving assistance to the user by taking into account the user's physical condition, the vehicle condition and the surrounding conditions. The surrounding conditions include, e.g., road, weather and traffic conditions, external to the vehicle. The vehicle condition concerns the conditions of the brakes, steering, tires, radiator, etc. of the vehicle. Signs of fatigue, stress and illness of the user are monitored by the control system to assess the user's physical condition.

  • Publication number: 20110019373
    Abstract: The invention relates to an arrangement for sensing ambient conditions in electric equipment. These conditions may include verification of the user, the location of the equipment and various properties of the environment. The invention is preferably applied in mobile terminals. One idea of the invention is to provide a sensor arrangement with a substrate (663) that forms at least part of a sensor, and also serves as a substrate for other sensors (695-698). The substrate is preferably flexible so that it can be formed in a shape which is follows the shape of the device cover. The invention also describes a way to create two- or three-dimensional electrode structures that can be used to optimize the performance of the sensor. When the surface structure is designed to follow the shape of a finger, a very small pressure is required when sliding the finger along the sensor surface. This way the use of the sensor is ergonomic and the measurement is made very reliable.

  • Publication number: 20100283488
    Abstract: A sample measurement device (110), in which a biosensor (30) having an electrode is mounted, voltage is applied to the electrode, and the concentration of a specific component in a sample deposited on the biosensor (30) is measured, comprises a voltage source (19) configured to apply voltage to the electrode, a time measurement component (22), and a controller (18) configured to control the voltage to be applied and measure the concentration of the specific component. The time measurement component (22) measures a detection time, which is the length of time between the mounting of the biosensor (30) and the deposition of a sample on the biosensor (30). The controller (18) changes a set value for measuring the concentration of a specific component according to the detection time. Consequently, measurement accuracy can be improved regardless of the temperature of the biosensor (30).

  • Patent number: 7787938
    Abstract: Body temperature measurements are obtained by scanning a thermal radiation sensor across the side of the forehead over the temporal artery. A peak temperature measurement is processed to compute an internal temperature of the body as a function of ambient temperature and the sensed surface temperature. The function includes a weighted difference of surface temperature and ambient temperature, the weighting being varied with target temperature through a minimum in the range of 96° F. and 100° F. The radiation sensor views the target surface through an emissivity compensating cup which is spaced from the skin by a circular lip of low thermal conductivity.
